A conventional straight boom lift typically includes a single telescopic boom which enables the platform to be positioned from low angles (usually below horizontal) to high angles (around 75-degrees above horizontal). A single tower articulated boom lift typically includes two booms connected by an upright. 417 0 obj <> endobj Underground Services The weight of a MEWP may cause damage to sewers, drains, manholes and gas and water mains. When the alarm sounds, the operator must lower the boom and reposition to a firm, level surface. All work at height equipment, as detailed within this specification standard in the range of Motion a! Work height is actually a more important dimension than platform height when you are qualifying a machine for a jobsite. Paved areas, such as footpaths, may look strong but could have weaker ground or shallow services underneath. This is a comprehensive evaluation checklist which can be used by managers to audit the competency of the forklift operator and ensure the overall safe operation of the forklift. Unpacking Construction Site Safety provides a different perspective of safety in practice. . The upper boom is pinned to the upright with its own lift cylinder which can be raised or lowered in angle with a full range of motion regardless of the position of the tower boom. Total Number of Credits for MEWPs Electives: 25. Each machine has its own envelope control. This upright is held in a vertical orientation as the lower boom or tower is raised at an angle. In all, the dynamic stability of the MEWP can be calculated accurately by ADAMS, in the meantime, the overload operation test (1.5 times rated load) must be performed on the 5 cross slope before the MEWP are selled, and so long as the minimum dynamic stability safety coefficient is no less than 0.1, the MEWP are proved stability and safety. Several significant qualitative changes are found. Utilize fall protection equipment Face the machine. N. The MEWP shall not be operated on grades, slopes, ramps, or cambers exceeding those for which the MEWP is rated by the manufacturer. Many accidents or equipment damage happens when operators don't fully understand the equipment. In the past, MEWP guidance from the safety group was aimed at outrigger-enabled equipment; the new information now also references importance of ground stability and understanding load-bearing capacity for self-propelled and crawler-mounted aerials. Forward stability positions are the most critical when the main boom is extended near a horizontal angle and when the tower is fully raised in angle but retracted in length. 6. Front-Arm Swing Occurs when the front boom arms (elevate assembly) of an articulating boom extend beyond any edge of the chassis during rotation. Look out for the warning lights on the control panel. . Moving from hard ground to soft may cause instability and overturn. 4.
